Spring Cloud Contract provider返回请求相同

Question

  Contract.make {
  request {
    method 'POST'
    url '/provider/foo'
    body(
        "foo": $(regex("[a-zA-Z0-9]{20}"))          
    )
  }
  response {
    status 200
    body(
        "fooResponse": fromRequest().body("\$.foo")
    )
 }

{
  "id" : "a80c0871-f4c0-49e3-8cc1-94de39899669",
  "request" : {
    "url" : "/provider/foo",
    "method" : "POST",
    "bodyPatterns" : [ {
      "matchesJsonPath" : "$[?(@.['foo'] =~ /[a-zA-Z0-9]{20}/)]"
    } ]
  },
  "response" : {
    "status" : 200,
    "body" : "{\"fooResponse\":\"{{{jsonpath this '$.foo'}}}\"}",
    "transformers" : [ "response-template" ]
  },
  "uuid" : "a80c0871-f4c0-49e3-8cc1-94de39899669",
  "scenarioName" : "scenarioReturnSameAsRequest",
  "requiredScenarioState" : "Started"
}

但当我的代码调用提供程序时,将foo作为任何文本,wiremock返回：

{
    "fooResponse" : "{{{jsonpath this '$.foo'}}}"
}

如何构建一个与请求体响应相同参数的契约？

编辑

  Contract.make {
  request {
    method 'POST'
    url '/provider/foo'
    body(
        "foo": $(regex("[a-zA-Z0-9]{20}"))          
    )
  }
  response {
    status 200
    body(
        "fooResponse": "fooValue"
    )
 }

{
    "fooResponse" : "fooValue"
}

也许不支持从请求获取正则表达式值？

我认为映射应该包含request.body而不是this。另外，我想知道您是否需要使用{三次或仅使用两次。或者您需要转义这些？

可能的映射：

"response" : {
  "status" : 200,
  "body" : "{\"fooResponse\":\"{{jsonpath request.body '$.foo'}}\"}",
  "transformers" : [ "response-template" ]
},
